Working Papers and Work in Progress

  1. A Rational Theory of Mutual Funds' Attention Allocation
    with Marcin Kacperczyk and Stijn Van Nieuwerburgh
    Download Paper | Technical Appendix
    Mutual funds should monitor payoff-relevant information and use that information to form profitable portfolios. We solve a model to determine what information funds should monitor and test the model's predictions with fund portfolio data.

  2. Understanding Uncertainty Shocks and the Role of the Black Swan with Anna Orlik
    Download Paper | Slides | Non-technical Summary | FAQs | Uncertainty Index (xls file)
    Where do uncertainty shocks come from? When a Bayesian forecaster updates his non-linear forecast model each period, his estimated probability of tail events fluctuates. Results measure this effect and show it generates large swings in uncertainty.

  3. Should We Regulate Financial Information? with Pablo Kurlat
    Download Paper | Slides
    We explore the costs and benefits of regulations that require asset issuers to disclose information about future asset payoffs.

  4. Information Globalization, Risk Sharing, and International Trade
    with Isaac Baley and Michael Waugh
    Download Paper
    | Slides
    When countries have more information about each other, they trade less and share less risk, but achieve higher utility.

  5. Black Swans and the Many Shades of Uncertainty
    with Anna Orlik and Nic Kozeniauskas
    Download Paper
    Measures of micro, macro and higher-order uncertainty are conceptually distinct, but covary closely. Standard models do not explain magnitudes. Time-varying black swan risk does.

  6. Germs, Social Networks and Growth, with Alessandra Fogli
    Download Paper | Abstract (html) | Slides
    When societies form their social institutions, they do so, in part, to protect themselves from the spread of disease. But such social structures may inhibit the diffusion of new technologies and restrain economic development.

Published and Forthcoming Work

  1. Time-Varying Fund Manager Skill,
    with Marcin Kacperczyk and Stijn Van Nieuwerburgh
    Journal of Finance, August 2014
    Download Paper
    Using data on fund managers' holdings and returns, we find evidence that managers' stock-picking and market-timing skills change over the business cycle.

  2. Leadership, Coordination and Mission-Driven Management,
    with Patrick Bolton and Markus Brunnermeier
    Review of Economic Studies, April 2013, v.80(2), p.512-537.
    Download Paper | Abstract (html) | Technical Appendix | Slides
    Leaders face a time-inconsistency problem: They want to commit so that their followers will be coordinated and act as a team. But ex-post, they want to adapt to a changing environment. In such a setting, overconfident leaders can achieve better outcomes.
    Awarded the 2008 JP Morgan Prize for the best paper at the Utah Winter Finance Conference

  4. Nature or Nurture? Learning and the Geography of Female Labor Force Participation, with Alessandra Fogli
    Econometrica, July 2011, v.79(4), p.1103-1138.
    Download Paper | Abstract (html) | Supplementary Appendix | BibTeX Citation | Slides
    The increase in female labor force participation and its geographic pattern was driven partly by the diffusion of information about the effects of maternal employment on childhood development.
    A non-technical summary in The Region magazine

  5. Information Acquisition and Under-Diversification,
    with Stijn Van Nieuwerburgh
    Review of Economic Studies, April 2010, v. 77(2), p.779-805.
    Download Paper | Abstract (html) | Technical Appendix | BibTeX Citation
    Before investors solve a standard n-asset portfolio problem, they choose what payoff-relevant information to acquire. We explore various preferences and learning technologies and show the investment patterns that result from each.

  6. Income Dispersion and Counter-Cyclical Markups, with Chris Edmond
    Journal of Monetary Economics, September 2009, v. 56(6), p.791-804.
    Download Paper | Abstract (html) | BibTeX Citation
    Counter-cyclical income dispersion can account quantitatively for the counter-cyclicality of markups in a simple, neoclassical business cycle model. This explanation is consistent with many cross-sectional and long-run facts.

  7. Ratings Shopping and Asset Complexity: A Theory of Ratings Inflation, with Vasiliki Skreta
    Journal of Monetary Economics, July 2009, v.56(5), p.678-695.
    Download Paper | Abstract (html) | BibTeX Citation | Slides
    The more complex assets issued in the mid-2000's were harder to rate accurately. Noisier ratings gave asset issuers an incentive to shop around for the best rating. This could explain the emergence of ratings bias.
    Awarded Glucksman Institute Research Prize - 3rd place

  8. Information Immobility and the Home Bias Puzzle,
    with Stijn Van Nieuwerburgh
    Journal of Finance, June 2009, v. 64(3), p.1187-1215
    Download Paper | Abstract (html) | Technical Appendix | BibTeX Citation
    Investors profit most from information that is very different from what other investors know. Therefore, if a home investor starts out knowing more than foreigners do about the future payoffs of home assets, their optimal research strategy is to learn more about home assets, and buy more home assets on average.
    Awarded Glucksman Institute Research Prize - 1st place
    Awarded best paper prize in investments by Financial Management Association

  9. Knowing What Others Know: Coordination Motives in Information Acquisition, with Christian Hellwig
    Review of Economic Studies, 2009, v.76, pp.223-251
    Download Paper | Abstract (html) | Technical Appendix | BibTeX Citation | Slides
    When agents choose information to acquire before playing a strategic game, information choices inherit the strategic motives in actions. Specifically, in price-setting models with information choice, complementarity in price-setting makes information acquisition a complement. This helps delay price adjustment but can generate multiple equilibria.

  10. Learning About Reform: Time-Varying Support for Structural Adjustment
    International Review of Economics and Finance, March 2009, v.19(2), p.192-206.
    Download Paper | Abstract (html) | BibTeX Citation
    A reform that causes sectoral reallocation produces temporary unemployment. As workers are gradually re-employed, they learn about the costs and benefits of reform, and political support for the reform changes.

  11. Aggregate Shocks or Aggregate Information? Costly Information and Business Cycle Comovement, with Justin Wolfers
    Journal of Monetary Economics, v. 54(S), Sept 2007, pp.37-55
    Download Paper | Abstract (html) | Technical Appendix | BibTeX Citation | Slides
    Because of the high fixed costs of information gathering and the low cost of replication, many firms buy cheap aggregate information instead of expensive sector -specific information. As a result, production decisions overweight aggregate shocks and covary more than multi-sector models predict.

  12. Information Markets and the Comovement of Asset Prices
    Review of Economic Studies, July 2006, v.73, p.823-845.
    Download Paper | Abstract (html) | BibTeX Citation
    When market participants buy information about the future value of an asset from an information market, asset prices and returns covary more than standard pricing models predict.

  13. Media Frenzies in Markets for Financial Information
    American Economic Review, June 2006, v.96(3), p.577-601.
    Download Paper | Abstract (html) | BibTeX Citation
    In frenzies, market participants appear to coordinate - they buy the same assets at the same time. Coordination motives in information acquisition generate investment patterns that mimic coordinated investment.

  14. Learning Asymmetries in Real Business Cycles,
    with Stijn Van Nieuwerburgh
    Journal of Monetary Economics, May 2006, v.53(4), p.753-772.
    Download Paper | Abstract (html) | BibTeX Citation
    More economic activity generates higher-precision information about productivity, which makes business cycle downturns sharper than recoveries. The calibrated model explains the extent of business cycle asymmetry.

  15. Slow Boom, Sudden Crash
    Journal of Economic Theory October 2005, v.124(2), p.230-257.
    Download Paper | Abstract (html) | BibTeX Citation
    The productivity of an investment can only be observed if the investment is undertaken. In high investment periods, more signals speed up learning and hasten crashes, relative to booms.

    Download Paper (with Appendix) | Abstract (html) | BibTeX Citation
    The "Information Immobility" paper raises a question: Aren't foreign assets a valuable hedge against labor income risk? In this extension, labor income is a source of risk, but also a source of comparative information advantage in trading home assets.
